Iron is an important substance that our body needs in minute amounts. Daily ingestion of iron is needed for the health of red blood cells and muscle proteins, as well as the functioning of body cells. The normal body iron content in an adult is approximately 3-4 grams.

Iron Deficiency
Iron is a mineral our bodies need. Iron deficiency is a condition resulting from not enough iron in the body. It is the most common nutritional deficiency and the leading cause in the US. Iron deficiency is caused due to increased iron deficiency from diseases, nutritional deficiency, or blood loss and the body's inability to intake or absorb iron. Children, teen girls, pregnant women, and babies are at most risk for developing iron deficiency. Symptoms of iron deficiency include feeling weak and tired, decreased work or school performance, slow social development, difficulty maintaining body temperature, decreased immune function, and an inflamed tongue. Blood tests can confirm an iron deficiency in an individual. Treatment depends on the cause of the deficiency. Proper diet that includes recommended daily allowances of iron may prevent some cases of iron deficiency.

Nature vs. Nurture Theory (Genes vs. Environment)
In the nature vs. nurture debate, "nature" represents our genetic makeup. These are the genes you have inherited from your biological family, and that may affect your physical and mental health, for example, intelligence, disease, and psychological health. While "nurture" represents how our environment affects our intelligence, traits, personality, and mental and physical health. Studies have shown that a person's environment can alter his or her genes, and lower their risk of developing certain inherited diseases, conditions, and mental illnesses that run in his or her family. Researchers and doctors have found that particular physical traits like eye and skin color, and diseases like Huntington's chorea are the result of genetic inheritance (inherited from a family member). However, patterns of thinking and behavior can be attributed to both nature and nurture (your genes and your environment). Moreover, researchers who study the brain have found overwhelming evidence that a person's genetic factors and his or her experiences guide and support brain development. The human brain produces new nerve cells (neurons) into adulthood, and these nerve cells can change the strength of their connections throughout life, which can affect intelligence and other factors.
